Finding city in Map visualisation

Hi Team,

I have created 2 report general view and focus view report.

In General view report, provided link to navigate to focus view report with respect to country(please see the below sccrenshot) 

and in focus view report, created map with respect to city. 

Suppose if i select United state from general view it navigated to united state focus view page.

For instance, the city of BERLIN exists in Germany but also in the USA.  i would like to see Berlin, USA  in united state focus view and not Berlin, Germany? Same like have more than 50 city names are similarly for other countries.

Could you please help me on this.
